If you have built up equity in your home and you are thinking about turning some of it into cash, a conventional cash-out refinance is one of the main ways to do it. The question most people ask first is how much they can take. The answer comes down to a single number lenders watch closely: the loan-to-value ratio, or LTV. Understanding that one figure tells you almost everything about the size of the check you can walk away with.
This guide explains how LTV limits work on a conventional cash-out refinance, why the property type changes the cap, and how to estimate your own number before you ever call a lender.
What a cash-out refinance actually does
A cash-out refinance replaces your current mortgage with a new, larger one. You pay off the old balance, and you receive the difference between the two loans in cash. The Consumer Financial Protection Bureau describes how these loans work and notes that borrowers often use the money to pay down other debt, cover home repairs, or handle a large expense.
The cash you receive is not free money. It is your own equity, converted from something you cannot spend into something you can, and you pay it back as part of a bigger mortgage. That framing matters, because it keeps the decision honest.
How loan-to-value works
Loan-to-value is the size of your loan divided by the appraised value of your home, written as a percentage. If your home appraises for 400,000 dollars and your new loan is 300,000 dollars, your LTV is 75 percent. The lower the number, the more equity you are keeping in the home.
On a cash-out refinance, the LTV is calculated on the new, larger loan, including the cash you take. That is the figure the limit applies to.
The 80 percent rule on a primary home
For a conventional cash-out refinance on a one-unit primary residence, the loan is generally capped at 80 percent of the home's appraised value. In plain terms, you have to leave at least 20 percent of your equity in the house. You cannot borrow it all out.
Here is how that plays out. Suppose your home appraises for 400,000 dollars. Eighty percent of that is 320,000 dollars, which is the largest new loan you could take. If you still owe 250,000 dollars on your current mortgage, the difference, about 70,000 dollars, is the most you could receive in cash before closing costs. Subtract those costs and you have your realistic number.
Why investment and multi-unit properties are capped lower
The 80 percent figure applies to a one-unit home you live in. Once the property is something else, the limit usually tightens. Cash-out refinances on second homes, on two-to-four-unit properties, and on investment properties are commonly held to a lower LTV, often around 75 percent, because the lender takes on more risk when the home is not your primary residence. If you own a duplex you live in or a rental across town, expect a smaller slice of the value to be available as cash. The exact figure depends on the property and the loan, so confirm it for your situation.
The appraisal decides your ceiling
Your LTV limit is only as good as your appraised value, because the percentage is applied to the appraisal, not to what you think the home is worth or what you paid for it. If the appraisal comes in lower than expected, your available cash shrinks along with it. This is worth keeping in mind before you plan around a specific dollar figure. A loan officer can look at recent sales in your area and give you a grounded estimate, but the appraisal is the number that sets your true ceiling.
Value is more than the cash you receive
It is easy to focus on the largest amount you can pull out. The more useful question is what the money costs and what it does for you. A cash-out refinance resets your mortgage, often to a fresh 30-year term, and it can change your rate and your monthly payment. Pulling out equity means paying interest on that amount for years, so the real comparison is the total cost of the cash against the value of what you do with it.
There is one point the numbers make plainly. Turning unsecured debt, like credit cards, into mortgage debt moves that balance onto your house. The CFPB notes that paying non-mortgage debts with mortgage debt can raise the risk of foreclosure, because the debt is now tied to your home. For many families the trade is still worth it, since the mortgage may carry a lower rate and a single payment is easier to manage. The point is to make that choice with open eyes rather than on the promise of a lower monthly bill alone.
How to estimate your available cash
You can sketch your own number in a few minutes:
- Estimate your home's value. A recent sale of a similar home nearby is a reasonable starting point.
- Multiply that value by 0.80 for a primary home, or by about 0.75 for an investment or multi-unit property. That is your maximum new loan.
- Subtract what you still owe on your current mortgage. What remains is your rough cash before costs.
- Subtract estimated closing costs to land on a realistic figure.
Treat this as an estimate, not a promise. The appraisal and your full financial picture set the final number, but this math tells you quickly whether a cash-out refinance is worth a real conversation.

Frequently asked questions
How much can I cash out on a conventional refinance?
On a one-unit primary home, your new loan is generally capped at 80 percent of the appraised value. Your cash is that amount minus what you still owe and minus closing costs. Investment and multi-unit properties are usually capped lower.
Why do I have to leave 20 percent equity in my home?
The 80 percent limit is built into conventional cash-out guidelines. Keeping equity in the home protects both you and the lender if values shift, and it is a large part of why the program stays stable over time.
Is the limit based on what I paid or what the home is worth now?
On what it is worth now, as set by the appraisal. That is why an accurate value estimate matters before you plan around a specific amount of cash.
Can I do a cash-out refinance on a rental property?
Yes, but the LTV limit is usually lower than on a primary home, often around 75 percent. You keep more equity in the property because the lender treats a non-owner-occupied home as higher risk.
Should I use a cash-out refinance to pay off credit cards?
It can help, since mortgage debt often carries a lower rate and consolidates several payments into one. The trade-off is that the balance is now secured by your home. Look at the total cost and the risk, not just the lower monthly payment, and ask a loan officer to run both.
Does a cash-out refinance always raise my monthly payment?
Not always. A larger balance pushes the payment up, while a lower rate or a longer term can pull it down. The only way to know is to see your specific numbers side by side, which a loan officer can prepare for you.
What the LTV limit protects you from
The 20 percent cushion can feel like the rule keeping you from your own money. It is closer to a seatbelt. Home values move, and a borrower who pulls out every last dollar of equity has no room if the market softens. The limit keeps you from ending up owing more than the home is worth, which is the situation that traps people when they need to sell or refinance again. So while the cap sets a ceiling on today's cash, it also preserves the flexibility you may want later. Careful owners treat the limit as a planning tool rather than an obstacle, and they decide how much of the available room they actually need instead of taking the maximum by reflex.
Can I take less than the maximum cash?
Yes, and often you should. Borrowing only what you need keeps your payment lower, your equity higher, and your options open for the future. The limit is a ceiling, not a target, and there is no rule that says you have to reach it.
